With the popularization of electric vehicles (EVs), the out-of-order charging behaviors of large numbers of EVs will bring new challenges to the safe and economic operation of power systems. This paper studies an optimal charging strategy for EVs. For that a typical urban zone is divided into four regions, a regional time-of-use …
Under the goal of "Emission peak, carbon-neutral", it has become an inevitable choice to build a new power system with new energy as the mainstay in the 14th Five-Year Plan period. Determining how to make better use of economic incentives to mobilize demand-side resources and tap demand-side response potential is of great practical significance to …
As shown in Fig. 5(a), the electricity price is low at 00:00–08:00 when electricity consumption is required, and EVs are guided to charge at this stage. The electricity price is higher during the period of 16:00–21:00 in the peak load period, the charging behavior is reduced and EVs are guided to discharge during this period.

The peak-valley time-of-use electricity price can reduce the peak-valley difference of the power system, improve the load factor and operational reliability of the power system, and bring huge economic and social benefits. With the continuous development of society, the resident load will gradually become the main component of …
By simulating household electricity load profiles, an electricity price policy response model and a residential PVP policy optimization model, are constructed …

The table below shows prices for C&I users with a consumption of 35-110 kW purchasing electricity from the State Grid Corporation of China (SGCC). According to the table, in July 2023, 24 regions saw the peak-to-valley spread exceed RMB 0.7/kWh. Among them, 90% experienced month-on-month increases, and 70% year-on-year …
Specifically, we compare the impact of the peak-trough electricity price policy (PP policy) and the uniform electricity price policy (UP policy) based on electricity price cap regulation. The findings are as follows: (1) Regardless of the cap, the UP policy consistently results in no lower renewable energy input level and total …
1. Introduction. The goal of electricity demand-side management is to shave peaks and to fill valleys through an appropriate mechanism design to change the electricity consumption behaviour of users, that is, to use less electricity during the peak hours of the grid load and more electricity during the valley hours, which can optimise …

Time-of-use(TOU)electricity price is an effective price-based demand response strategy,which plays an important role on load shifting. The essence of TOU pricing is to determine its level so as to provide adequate and effective pricing signal. Firstly,the reaction of customers to TOU electricity price is analyzed based on the price-based demand …
The peak and off-peak pricing is the simplest form of ToU tariff to deliver peak-load reduction (The UK Department of Energy and Climage Change, 2012) cause the simple nature of the peak and off-peak pricing, it does not require any complex two-way communication system (Torriti, 2016).The small price volatility of the peak and off-peak …
Peak-valley pricing and flat pricing of air conditioner. Full size table. The electricity cost of air conditioner according to peak-valley pricing S1_2 = 9.4964 (yuan/day) and flat pricing S2_2 = 9.3863 (yuan/day), the difference ΔKtype2 = S1_2 - S2_2 = 0.1101 (yuan/day). For air conditioner, it is more advantageous to use flat pricing.
The simulation shows that under the EV charging time-of-use price mechanism with a 50% price increase during peak hours and a 50% price reduction during valley hours, the total power cost of Beijing-West Inner Mongolia power systems is …
Peak-valley time-of-use (TOU) price is a demand response measure of demand-side management [1-3]. TOU guides users to adopt a reasonable power consumption structure and mode through an …
The peak and off-peak pricing differentiates electricity price between peak and off-peak period during a day, see Fig. 1. In the peak hours consumers will be charged with higher electricity price whereas in the off-peak hours with lower price ( …
The policy also introduced a seasonal pricing mechanism – in January, July, August and December, power prices will be higher than other months. The electricity price during peak and valley periods will increase 71% and decrease 53%, respectively, compared to shoulder electricity prices. Furthermore, a 20% mark-up on top of the peak …
Because the declining value of variable renewable energy may be especially problematic in wholesale electricity markets (WEMs), this study argues that …
The main purpose for the peak and off-peak pricing program is to induce energy consumers to eliminate their demand in the peak period by shifting peak load to off-peak period. The peak and off-peak pricing allows a 30–50% price hike during peak hours and a 30–50% discount during off-peak period (State Council, 1985).
First, we analyse the policy text according to the policy content refined into five parts: (1) the specific degree of electricity price fluctuation up and down; (2) the specific times corresponding to the floating prices; (3) the purpose of the electricity price reform is to achieve clean energy consumption and to balance the peak of the …
Secondly,every party''s expected objective is discussed when an incentive peak-valley time-of-use(shorted as TOU) electricity price is designed,which is specially applied to ice storage air conditioning systems.Meanwhile,various physics and management constraints are also included.
The combined operation of hybrid wind power and a battery energy storage system can be used to convert cheap valley energy to expensive peak energy, thus improving the economic benefits …
The ongoing electricity crisis has led to the top authority''s decision to change the nation''s electricity pricing—more precisely, to reform the electricity pricing in a very difficult focus. In fact, since 2016, China has been in a multi-dimension electricity market reform where pricing reform is one of the core elements.
Energy users could leverage widened peak-valley price differentials to optimise energy usage for cost savings, such as considering energy storage solutions as …

In other words, the effect of peak and valley shifting of TOU-IBTs policy is based on the increase of the total use of users, which is contradictory to the goal of energy conversation. The main purpose of peak and valley shifting of TOU pricing is to reduce electricity use at peak times, or to shift the electricity use at peak time to …
